<h1>YUI Loader Utility Example: Loading the YUI Calendar Control with the YUI Loader Utility</h1>

<p>In this example, we bring a YUI component onto the page using the <a href="http://developer.yahoo.com/yui/loader/">YUI Loader Utility</a>. This example implements YUI Loader via a <code>YAHOO.util.YUILoader</code> instance.  We load the YUI Loader script file, then specify in configuration which component we want loaded on the page &mdash; and what we want to do once it <em>is</em> loaded.</p>

<div id="calendar_container"></div>

<script src="../../build/yuiloader/yuiloader.js"></script>

<script>

    var loader = new YAHOO.util.YUILoader({

        require: ['calendar'], // what components?

        base: '../../build/',//where do they live?

		//filter: "DEBUG", 	//use debug versions (or apply some
							//some other filter?

		//loadOptional: true, //load all optional dependencies?

		//onSuccess is the function that YUI Loader
		//should call when all components are successfully loaded.
        onSuccess: function() {
			//Once the YUI Calendar Control and dependencies are on
			//the page, we'll verify that our target container is 
			//available in the DOM and then instantiate a default
			//calendar into it:
			YAHOO.util.Event.onAvailable("calendar_container", function() {
				var myCal = new YAHOO.widget.Calendar("mycal_id", "calendar_container");
				myCal.render();
			})
         },

        // should a failure occur, the onFailure function will be executed
        onFailure: function(o) {
            alert("error: " + YAHOO.lang.dump(o));
        }

     });

    // Calculate the dependency and insert the required scripts and css resources
    // into the document
    loader.insert();

</script>
